The 2nd  International Conference on “Green Technologies for Sustainable Water 2019”, was organized by Ho Chi Minh City  University of Technology, Vietnam from 1 to 5 December, 2019. The aim of this conference was to provide a forum  for exchanging experience, knowledge and innovative ideas on environmental pollution and water and wastewater related topics. More  than 250 participants from 35 countries participated in this conference. Prof. Visu was invited one of the 8 Key note speakers, and he presented and interesting presentation on “Mega Trends in Water and Wastewater Treatment Processes”.

This presentation  highlighted the key mega trends that are shaping the water and wastewater market during the next decade and explored the investment opportunities that are arising from these trends. Market opportunities related to the water sector are expected to reach USD 1 trillion by 2025. Companies that are early to respond and take steps to exploit the market opportunities associated with these water-related challenges are more likely to gain a competitive advantage and achieve commercial success.

One of the fastest growing water business at the moment is purified bottle water service. Since the home-based water purification systems require considerable initial investment and constant servicing, the purified bottle water as an ideal alternative. Similarly, point-of-use water dispensing machines are increasingly deployed in south  and south east Asia. They offer purified water in every location and IoT will help in increasing its visibility. Carbon neutral wastewater treatment, membrane bioreactors and RO systems, concept of co-location of membrane desalination plants with power generation plants, decentralized treatment systems, and IoT in water sector are increasingly becoming popular in every part of the world which may dominate the next decade.

Current educational system related to water and wastewater sector is composed of hydraulic, civil and chemical engineering aspects which will not be enough to  address problems related to water and wastewater sector. In fact it should be a combination of diverse backgrounds like energy, climate change, green technology, IoT, etc.. Therefore it is a timely challenge to revamp the future engineers with multi-disciplinary knowledge to prepare them for the trends in water and wastewater sector in the next decade.
